Why does my heater fuse keep blowing?
Blown fuses usually result either from an appliance putting too much strain on the fuse or by an electrical short in the system. Since some furnaces can require a lot of electricity, homeowners must ensure that they have an adequate electrical system to support the furnace.
What is a fusible link on an electric heater?
The fusible links are used as a safety device to break the electric circuit in an electric furnace if the furnace overheats. The FUS01312 is set to break the circuit when an electric furnace reaches a temperature of 117 degrees Celsius or 242 degrees Fahrenheit.
Can a blown fuse cause no heat?
A blown fuse is a symptom not a cause. If a new fuse blows as soon as the blower is turned on, the heater circuit or motor may have a short that should be investigated. If the fuse lasts a while and then blows, the fan motor is probably running hot due to worn brushes and/or bushings and should be replaced.
How would you tell if a fusible link is blown?
The fusible link is essentially an in line fuse on the positive terminal of the battery. To determine if the fusible link has been blown , one test lead of your ohmmeter should be on the positive terminal of the battery and the other test lead should be on the end of the fusible link going to the circuit it protects.
What happens when a fusible link goes bad?
When it fails, it will break the continuity in the rest of the circuit, preventing damage to other components down the line. A fusible link typically costs a couple of bucks and can be replaced in 30 minutes.
What to do if your Mr heater keeps blowing fuse?
We will start by disconnecting the components like limits, pressure switches etc and making sure fuse does not blow with just the board connected to the 24v from transformer. If fuse blows with nothing but the transformer wires to board then board is shorted and will need to be replaced.

Disconnect everything in the circle and see if fuse still blows. Finding a short can be difficult as the only way to find it is to determine what has to be taken out of the circuit to prevent it from blowing.
What happens when a fuse melts on a space heater?
The thermal cut-off for these fuses usually occurs through both radial and axial leads. In the event that a burst of electrical current surges through your space heater, the fuse will melt and this will immediately stop the electrical current from continuously flowing through your device.
Can a space heater blow an extension cord?
As mentioned above, you should not use extension cords for space heaters. The heater should already come with a long, sturdy cord that will be able to bear the load.
